Okay - so far so good

I added some Polyquat 60....

about 90 minutes ago, I added the ascorbic acid with the filter on "recirculate"

stains are gone - looks great - liner looks blues again !! Instead of brownish-greenish

30 minutes later I added the Metal Free. Put the filter back on "filter".

BIG question from my son and family:

"When can we swim - we want to swim today"?????

Can I add a little chlorine to bring it up to 1.0, so we can swim in a couple of hours? I'll check the PH and make sure it is around 7.1 -7.2 (no higher and no lower)
